There is an organization called Project Embrace, located in the UK, that is embarking on a wonderful journey! They are working on establishing billboards that feature natural hair styles.
With little girls like Tiana being told that they can't wear Locs to school, this project is right on time. You can Like their Facebook page here: https://www.facebook.com/ProjectEmbraceUK.
Please check out the conceptual video they made showing billboards with beautiful Locs and other African textured hair. You're in for a treat!
